Step 5. Enable Data Encryption
At the Settings step of the wizard, use the Enable encryption check box to choose whether you want to encrypt backup files stored in the selected Amazon S3 bucket folder. If you enable encryption, specify a password that will be used to encrypt data.
Veeam Backup for AWS encrypts backup files in S3 repositories the same way as Veeam Backup & Replication encrypts backup files in backup repositories. For more information, see S3 Repository Encryption.
If you have chosen an existing folder at the Repository step of the wizard, and if encryption is enabled for this folder at the S3 repository level, you must provide the currently used for encryption password to let Veeam Backup for AWS access this folder and add it as an S3 repository.
